REFRIGERATOR-DRAIN.

Application filed November 19, 1915.

o @ZZ 'to/tom it' may concern.'

Be it known that I, 'llmnnr J. Gwrnn, a citizen of the United States of America` residing at New York city, New York, have invented a new and useful Refrigerator- Drain, of which the following is a specification.

My invention relates to improvement in refrigerator construction and the object of the present invention is to provide an irn- `prmeddrain outlet which is economical7 siniplefdurable. and which may be readily cleanedjand which will furthermore operate to prevent air from entering the refrigera tor via said outlet. y

i[n the accompanying drawing: Figure l is a liront elevation illustratinge; a refrigerator of conventional forni and provided with my improvement. Fig. 2 is a relatively enlarged sectional view oi" details. Fig. 8 is a plan View' of a detached detail.

1 represents a refrigerator easing of so itable form. Alin this instance the ice chest is located at the upper part 2 of the casing.

3 t are telescopic sections et a drain pipe by which the water from the upper partA of the refrigerator, due to melting ice, is conveyed to the drain outlet.

5 is the outlet end of the drain pipe at,

the bottom of the refrigerator. This outlet end 5 is trapped by means et a bellshaped trap 6 which partially overstands the upper end .oit the pipe 5 and projects into a channel around said .upper end 'as4 shown in Fig. 2. This trap bell 6 is carried by a perforated plate? preferably provided with a flange 8 with which flange the lower seetion"4= of the telescopic pipe engages, best seenin Fig. 2, so that said parts Inutually steady" one another, also, so as to prevent leakage.

5a' is an v annular wall projecting` outwardlyv and upwardly from the pipe 5 near to but below its upper end. The inner surface ot' this wall is threaded.

9 is an annular member having a flange 10. The sidewall of this annular member below the flange 10 is threaded. to tit into the threaded part of the wall 5 while the flange l0 overstands the upper edge et' said wall. s

'I 21:1 is the interior lining cf the refrigeraztor. This lining is perforatedl in line with 'the drain pipe 4; to receive the outlet pipe and the associated parts. The edge of the Specification of Letters Patent.

opening in the lining ll is depressed ap proximately to the thickness of the flange l0, so that when the annulus 9 is screwed into the wall 5, the fiange l0 will operate as a nut to tightly clamp down upon the lining ll and hold the parts assembled as shown in Fig. 2. The inner edge ofthe ring 9 may also have a depressed seat as shown in Fig. 2`1tor supporting the plate 7 and bell G thus holdingr the parts in the proper position whereby when all the parts are assembled ready for use they will be firmly held against accidental displacement. As the ice melts in the upper part of the refrigerator, the water will run down the pipe 3--Lland through the perforations in the plate 7 until the channel around the upper end ot the outlet pipe 5 is filled to the level of said upper end, and thereafter as the water continues to run down the pipe sections f? and el., it will be discharged through the pipe By reason of the tact that the lower edge-otl the bell projects into the water in the channel around the upper end oit the pipe it fol lows that air cannot enter the chest through the drain pipe.

It it should be desired to clean the trap, the section al ot the pipe may be lifted thereby'unlocking the plate 7 which may then be lifted bodily with the bell (3 thus affording easy access to the channel around. pipe 5 and making it eorrespondingly easy to cleanse the plate 7. At such a time too, the inside of the lining ll. may be thoroughly cleaned. and since the flange l() lies substantially tiush with the inner surface 'othe lining` ll, the water used to wash the interior or" the refrigerator willl run freely. out through the discharge pipe.

lillhat l claim is:

l. n a refrigerator7 a bottom lining having a passage3 an outlet pipe located in line with said passage` an annular wall projecting outwardly and upwardly troni said outlet pipe from a point near to, but below the upper end thereof, to a point above the upper end thereoi with means tor securing said annular wall to said lining` around the opening therein, to torni a water tight joint, a bell trap over-standing the upper end oi said outlet pipe., the lower edge of the bell extending below the upper end of said pipe and being free therefrom and from the sur-- rounding wall, andv4 means for suspending with said passage, an

yet, clamping' means for i with i bell suspending menne haring; passages in line with said drain pil :o allow water to llow from the latter to the ouei pipe.

11n a refrigerator, a bottom lining` liaring apassage, an outlet pipe located in line annular wall projecta ing outwardly and upwardly ltr-om said outlet pipe from a point below the upper end thereof to a point above the upper end theresecuring said annular wall to said lining; around the (meningv therein to form a water-tight joint, a bell trap overstanding the upper end of said. outlet pipe, the lower edge of aid bell extending below the upper end or' said pipe, but being; free therefrom and from the Surround-- ing' wall,v and means toreuspending said bell in Said position, Suid suspending means, being mounted upon but independently removable from said clamping means, and a drain pipe leading` from above down to Said. outlet and eommunieating` therewith above said bell, said bell suspending means having pas sages in line with Said drain pipe to allow 'ater to flow from the latter to the outlet pipe.

3. In a refrigerator, a bottoni ing a passage,

lining haw anoutlet pipe located in line Said passage, an unnular wail groin-ie"- ing outufardly and upwrdly from ysaid outlet pipe from a point .below the upper enel thereof to a point above ol?, with means for securing said annular wall to said lining around the opening therein to form a watertight joint, an annular .recess in the upper partof said seCuring means around the opening therein, a perforated plate removably mounted in said .rec bell trap earried by said plate, the lower edge of the Same extending down to und around the upper end of said outlet pipe and .separated therefrom and from the surrounding annular wall, said perforated plate ha ving" an upuf'ardly projecting annular 'wall around. the perforations therein, and a drain pipe fitting said. annular wall.

l. ln a refrigerator, a bottom lining,r having a passage, an outlet pipe located in line with said pa nuage, an annular wall projecting outwardly. and upwardly from said outlet pipe 'from a point below the upper end thereof to a point above the upper end thereof, the in ner Surface of Said annular wall near its upper end being threaded,an annular Clamp ing,r member threaded on'its outside to en the upper end theregag'e the threaded part of the annular wall.'

said annular member having an outwardly projecting flange, whereby .said annular wall and annular member may clamp said lining between them, a perforated plate supported or l anmilar member and a bell trap susi o A l rom said perforated plate, said per toil red ilate beine" detachable from Said an neuerer J, Gwynn.
